OFFICE-I j j T STACK -"COV'ERJ Mich gan, have invented a new and usefulStack-Cover, of which the following is a specification.

TlL's invention'relates to improvements in temporary shelters orprotectors for hayand grain stacks and similar structures, and has forits object to improve the construction and increase the efficiency andutility of devices of this character.

With these and other obj ects in view, which will appear as the natureof the invention is better understood, the invention consists in certainnovel features of construction, as hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, andin whch corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation.

Figure 1 is a perspective view of a haystack with the improved deviceapplied to a portion of the same. Fig. 2 is an enlarged sectional detailillustrating the construction at the ridge portion of the device. Fig. 3is an enlarged perspective detail of portions of a pair of the plates,illustrating the coupling devices whereby they are detachably united.

The improved device comprises a plurality of sheet-metal plates 10,preferably of steel, and corrugated longitudinally, the corrugationsbeing of angular form and preferably with one side of each corrugationlonger than the other. The plates are arranged with their edgecorrugations overlapping, as shown, to cause the water and snow to flowfreely from the plates when they are d sposed in inclined positionlongitudinally. Hooks and loops are attached, respectively, to theterminal corrugation of one sheet and an intermediate corrugation of thenext or adjacent sheet, the loop (represented at 12) being rigidlyconnected to one sheet and the hook (represented at 11) being rigidlyconnected to the other sheet.

For the purpose of illustration the loop 11 is shown attached toterminal corrugation of one sheet and protrudes beyond the edge, whilethe hook 11 is attached to the second corrugation of the next sheet andprotrudes over the end corrugation of the same sheet.

I I Specification of Letters Patent. ApplicatiowfiledNovember 25, 1905.Serial Nor289j'o89- Patented May 29,1906.

The loops and hooks are arranged near the ends of the sheets, as shown.By this arrangement when the sheet having the loops is elevated at theoppositeside the loops will be in position toengage the-hooks of thenext sheet, and then when the elevated sheet is lowered into positionthe corrugation having the'loops attached will bear within the first icorrugation of: the sheet having the hooks and be firmly locked thereto.thus firmly united' and can beseparated only whendisposed at-an angle toeach other, as above noted.

The sheets are disposed upon the stack side by side with their edgesoverlapping and locked together by the loops and hooks, and can beseparated only when disposed in the relative angular position described,a position they could not assume when in position upon the stack. Theconnected sheets are thus in position to resist the action of the windand will not be displaced thereby. The plates or sheets are disposedupon the stack (represented at 13) at each side of the center, withtheir inner ends spaced apart to leave an open space to provideforventilation. By this means the whole stack may be covered andprotected by multiplying the plates to correspond to the size of thestack and with an open ventilating-space at the center along the ridge.

Disposed above the open central space is an inverted-V-shaped member 16,extending at the edges over the inner ends of the plates, as shown inFig. 2, and provided with a plurality of spaced standards 17 forinsertion into the body of the stack. Theshield 16 is thus maintained inspaced position above the rldge'portion of the stack, so that wh,le the.65 The sheetsare material of the stack is effectually protected the aircan freely circulate beneath it and within the open spaces between thecover plates or sheets and the stack and between the adjacent ends ofthe same. The member 16 thus serves as a water-shed to protect theotherwise uncovered space between the ends of the plates, while at thesame time permitting free circulation.

Spaced strips 18, preferably of wood, are placed between the stack 13and plates 10 to maintain the latter in uniform position and preventthem from sagging if the stack set. tles and also to provide forcirculation between the plates and stack. Attached to the lower ends ofthe plates 10 are rings 19, to

which rods 20 are connected, the rods carrying weights 21 to hold theplates in position and prevent displacement by the wind. The outer edgesof the end plates are also provided with rings 22, to which rods 23 andweights 24 are attached, as shown, for the same purpose. v

The plates may be of any required size to adapt the device toanyrequired size of stack.

Having thus described the invention, what is claimed is 1. A cover forstacks comprising a plurality of plates corrugated longitudinally withthe corrugations at the edges interlapping,

and hooks and loops the elements of which are rigidly connectedrespectively to the terminal corrugation of one plate and anintermediate corrugationof the next plate whereby the plates may becoupled and uncoupled only when disposed in inoperative position.

2. A device of the class described compris- 'ing a plurality of platescorrugated longitudinally with the corrugations at the edgesinterlapping and disposed upon the stack at 0pposite sides of the centerwith the inner ends spaced apart, hooks and loops the elements of whichare rigidly connected respectively to the terminal corrugations of oneplate and an intermediate corrugation of the next plate,

means'for detachably coupling said plates at their adjacent spaced ends,a ridge member of the plate and overlapping the same, and standardsdepending from said ridge member and adapted to be inserted into thestack.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
